4 Claims. (Cl. 254-86) The present invention relates to certain new and useful improvements in draft tongue elevating and supporting devices and has more particular reference to a device which is herein identified as a stand, the latter being characterized by a jack screw and the over-all means being especially adapted to hold the tongue of a trailer, such as a farm wagon, in a given plane to facilitate the step of hitching a tractor or the like thereto. v

As the introductory statement of the invention obviously implies, draft tongue elevating and supporting jacks and the like are not new. An example of a prior art device structurally and functionally similar to that to be hereinafter specically revealed is disclosed in a patent to L. B. Neighbour et al., 2,245,935 of June 1'7, 1941. As will be hereinafter clarified, the instant invention has to do with an analogous construction which is possessed of significant structural refinements and improvements which, taken in a cumulative manner, go to make up a novel contribution to this specific line of endeavor. An equally general object of the invention is to provide an adjustable hitching stand and ways and means wherein same is adaptably fastened on the tongue, whereby to provide a structure which is better adapted to serve intended purposes, is simple, practical, easy to attach and adjust and, is therefore, capable of meeting the apparent requirements of manufacturers and users alike.

Briefly summarized, the preferred embodiment Aof the invention is characterized by two essential units; namely, a novel adapter xture or clamp which is applicable to the draft tongue, and a complemental leg frame, the latter being slidably and pivotally connected with the adapter fixture and carrying a jack screw which is both adjustably and detachably connectable with said fix- .bers which are channel-.shaped in cross-section to provide keyways for coating end portions of:

the lower plate of the aforementioned adapter fixture.

Other objects and advantages will become more readily apparent from the following description and the accompanying sheet of illustrative drawings.

In the accompanying sheet of drawings, wherein like numerals are employed to designate like parts throughout the views: v

Figure l is a side elevational view showing a fragmentary portion of a trailer vehicle, wagon or the like with a draft tongue, showing the hitch means in readiness to be lined up and coupled and showing, in addition, the tongue supporting and line-up stand;

Figure 2 is a fragmentary view with the tongue in elevation and with the parts of the over-all stand construction partly in elevation but primarily in section;

Figure 3 is a view based on Figure 2 and showing in full and dotted lines the manner in which the leg frame or stand is lifted up to an outof-the-way transporting position; and

Figure 4 is a enlarged perspective view ofthe adapterA fixture.

Referring first to Figure l, the numeral 6 designates any suitable trailer vehicle.y This may y*be a farm wagon, a two-wheeled trailer cart, 'a manure spreader or the like, the same having supporting wheels 3 and a draft tongue I0 with suitable hitching elements l2 and I4. Thenumeral I6 designates a towing or other powering vehicle, such as a tractor, having a hitch member I8 for separable connection or coupling with the members or elements I2 and I4. These are obviously old parts.

The invention, as before stated, is characterized by two essential or primary units; namely, the adapter xture I8 on the one hand and the stand or leg frame unit 20, on the other. The unit I8 is in the nature of a two-part clamp and comprises a lower rectangular plate 22 which "underlies the draft tongue in the manner shown,

It is provided on its forward longitudinal -edge portion with a stand retaining clip or hook 24 which has a depending bill portion 26. The complemental top plate is also rectangular andis denoted by the numeral 28 and is shorter than the plate 22. It is secured by bolts 30 and nuts 32 to the plate 22. There is an arched bracket 34 formed integral with the intermediate portion of the upper plate and this has a notch 36 in one edge and detent bosses 38-38 associated therewith.r It is believed that these features 34 to 38 may be described, in a unitary sense, as a keeper.

1 The latter makes it possible to separably adjoin the two units I8 and 20. In practice, the unit I8 vjoinedv together at their lower; ends 'by an' angle iron 42. There is a simple cross-piece 44 between the upper ends and this is centrally apertured and provided with nut means 4B to accommodate the threaded shank of the jack screw.

3 The shank is denoted at 48 and is screwed through the nut and provided with a coupling head 50. Then, too, there is a crank handle 52 at the opposite end.

By scrutinizing the drawings and relative proportions of the parts carefully, the reader observe that it is necessary that `thelength .of the plate 28 be such that it swings freely -w-Itlziout obstruction through the slot defined by the 'leg frame, that is, the slot between the channel irons 40. On the other hand, extended end ,portions 54-54 of the bottom plate are both slida'bly 'and rotatably keyed in the channels of the rchannelirons. Thus, the channels become keyways.

Let it be assumed, then, that the unit I8 is Vclamped on the .intermediate portion of .thefdraft tongue I0 and is bolted .securely in place with the keeper slot 36 ldirected `toward the forward end of the trailer vehicle. The projecting end portions or keys 54--54 are .keyed in vthe keyways of the channehirons Ml. Consequently, the leg frame -20 is not only slida-ble up and .down in relation to the adapter fixture t8 vbut -is also pivot-ed thereon so that said frame maybe swung from the perpendicular or vertical .position in Figures l and 2 .to :the inclined out-of-the-way non-using position shown in full lines -in Figure V3. The intermediate dotted line position shows, too, `vthat said leg frame may be swung from the position shown in Figure 3 -to a position where Vthe headed end V50 of the jack screw is lined with the keeper notch 3S to 4tlc-ius .couple Athe jack .screw with the keeper and consequently to .couple the two units I8 and -20 together for operative association. Not only does this functioning of parts -couple the units -but it .also .provides aseparable connection and, more importantly, .provides a jack screw connection .between the -stand on .the one .hand and .the 'tongue .carried adapted fixture .t8 on the otherhand. Obviously, when the leg l frame is up and out of .the way, Vasshown tothe left in full `lines in Figure ,3., .the channel-.iron 42 is then .releasably vengaged with .the retaining hook 24, the latter serving .to .assist in .holding the leg .trame .in the -out-of-the-.way position. The leg .frame is, `oi course, quite .heavy .and `once it swings over to .the .leaning or inclined position showninFigureB, it is .substantially put.

Briefly, the following constitute advantages .of the .tongue supporting .and bitching stand, to wit:

-1. The level ofthe tongue or hitch being .sup- Aported .may be raised or l.lowered easily'bysimp'l-y turning the .crank in the .properdirection 2. When .the .stand is not inuseit may be folded back-on the .tongue .or hitch, out of the way,.and will stay in place.

3. .It is lightweight and strong. fabricated easily and at low cost.

4. .It is adjustable to any size tongue or -hitch and it .is not necessary to `drill any ho'le lin 'the tongue or hitch to attach/same. It .simply slides over the end .of the tongue or hitch and then .secured in .place by tightening the bolts.

It .is .though that persons .skilled .in the ,art .to

fIt .may be which the invention relates will'be able to obtain .a clear understandngof -the invention after considering the description in connection with the drawings. Therefore, a more'lengthy description isregarded as unnecessary.

vMlincr changes in shape, size and arrangement of details coming within the eld vof invention 4 claimed may be resorted to in actual practice, lf desired.

Having described the -invention, what is claimed 'as newis:

l. in combination, a mobile vehicle embodying .a horizontal draft tongue, an adapter fixture embodying upper .and lower plates bolted on the tongue, a .keeper Xed on the upper plate, and a 4leg frame embodying channel-shaped side members :slidably and pivotally connected with .the respective end portions of one of said plates, said 'frame lincluding a stationary jack-screw and .jack-screw being releasably engageable with said keeper.
